I've read the thread on this mail, and I confirm that bitmap eps gives poor results on diagrams and screen saves, unless the original size is retained. I'm surprised that tex2pdf doens't give better results, as it avoids backconversion of bitmappped eps produced from JPG, PNG and PDF bitmaps, if the native image lies in the same dir as the eps converted one. Was this the case ? Example: main.lyx document foo.png original bitmap foo.eps bitmapped eps (obtained e.g by convert foo.png foo.eps) all in the same dir: tex2pdf should provide a pdf with the image quality of the original png, and dvips/ps2pdf a pdf with a degraded quality depending mostly on resizing. -- Jean-Pierre
